This is a tetralogy consisting of The Shadow of the Torturer, The Claw of the Conciliator, The Sword of the Lictor, and The Citadel of the Autarch. When MattyDub gave them to me, he said, "I don't know how to talk about Gene Wolfe with someone who hasn't read it. I'm afraid everything I say will be a spoiler." I totally get what he's saying now, but I'll do my best anyway.
BotNS is about a young man named Severian, an orphan raised and trained by the Torturers' Guild. He is exiled for the sin of giving mercy to one of the torturers' clients and travels, well... everywhere. The world is Earth, but it's dying. The sun is so dim that stars can be seen during the day, and only the area near the equator can be said to be truly warm. The Autarch, ruler of Severian's people in the south, is threatened by war in the north and rebellion led by the mysterious Vodalus. Throughout the four books, Severian gets wrapped up in basically everything.
That's about all I can say without ruining anything. This book will blow your mind. Every time you think you've got things figured out, Severian (the narrator) drops a bomb as casually as when he tells you what he had for dinner or that he sharpened and oiled his sword again. It's like watching Fight Club on a loop and being surprised every time. That was easily my favorite thing about it.
On the down side, it was a little slow at points: the beginning is hard to get into, and the story takes a few detours (esp. towards the end) that, while I'm sure had some deeper meaning I totally missed, were hard for me not to skip so I could continue the plot.
Overall, Book of the New Sun is a classic, and it's easy to see why. Gene Wolfe does things that I never knew you could do in prose. Things I'm not supposed to do as I try to get published. But he does them really, really well. It's like nothing I've ever read.
